However, these products are very susceptible to spoilage and have a short shelf-life. In this research, edible coatings based on sodium alginate and its blends with ascorbic acid (a natural antioxidant and anti-browning agent) were applied on fresh-cut pineapple samples, and the changes in their physi-cochemical properties were monitored during 10 d of storage at 4°C. Initially, the surface of the coated fruits was brighter and statistically significant differences were not found between uncoated and coated samples (P<0.05); similar values were obtained in the parameters of soluble solids °Brix), pH (~3.74) and titratable acidity (~0.64%). During storage, coated samples were more protected against changes in appearance compared to uncoated fresh-cut pineapple samples. The current results will be beneficial for further research that focuses on the preservation of minimally processed fruits such as pineapple.application/pdfAgronomía ColombianaAgrocienciasartículo científico
